Screw sand washing machine is a machine which uses the buoyancy of water to separate dust and impurities from sand. With the agitation of the screw slice, the impurities will be washing off. Meanwhile, the fine sand and the coarse sand will be mixed uniformly while it is lifted up. Screw sand washing machine is designed according to the characteristics that materials with different particle size and density
have different settling velocity in the fluid. The particle with fine size and less density has a lower settling speed. Conversely, the particle with coarse size has a higher settling speed. With the agitation of the screw slice, you can get the purpose of separating dust and impurities from sand.
